A monograph on “The Marine Algae of Peru,” by Dr. Marshall 
very Howe of the Garden staff, was published on September 19, 
constituting volume 15 of the Memoirs of the Torrey Botanical 
The work comprises 185 pages of printed text, accom- 
panied by 66 plates and 44 text figures. The report is based 
Coker, now of the United States Bureau of Fisheries, while 
acting as fisheries expert to the Government of Peru in the 
years 1906, 1907, and 1908. Dr. Coker’s collection proves to 
een one of the largest and best in its, field ever made in 
South America. The author is now able to ascribe 123 species 
of marine algae to Peru—a number nearly double that previously 
own. Of these, 29 species appear to be new to science. The 
large proportion of novelties is due in part to the inclusion of a 
number of inconspicuous endophytes and epiphytes, which offered 
an essentially unworked field so far as South America was 
concerned. Dr. Coker was apparently the first collector of 
seaweeds in that region to use a dredge, a fact that may account 
for his finding certain species that seem to have been overlooked 
by his predecessors. Through an courtesy of the curators of 
various European herbaria, ae writer has been able to examine 
the original noone on which numerous species described from 
South America were based, and this circumstance a contributed 
much to the scientific value of the monograph. e report was 
prepared at the request of the Ministerio de Fomento of the 
Peruvian Government as a contribution to the knowledge of the 
aquatic resources of Peru, and the expense of publishing the 
paper has been met in a considerable part by a subsidy from the 
Government of Peru
